Anyone use Diablosport Predator programmer?

I have just installed a predator programmer and saw very little difference in performance. Has anyone else done this? It seemed to accellerate in the higher rpm's a little quicker but not $300 worth of gain. Did I do something wrong?

I am looking at my next investment being my first performance upgrade - a programmer. As of now, I am leaning toward the DiabloSport Predator. It seems like a good unit, and I like the fact that it can program my truck to run on E85 fuel (if Alberta ever gets an E85 station). I just want to see if anyone has any experience with the Predator or suggestions before I go shell out $400+ (Canadian) for this unit. Thanks.

I know there are already threads about these things, but the more recent, the better.

As Ive posted before I love my Diablo because of all the fine tuning you can do yourself. You have to take the time to play with it but its fun. I gave cascott325 some tuning tips with his and he says hes happy with the mods. Ive tried the other programmers and even custom tunes but I like the Diablo best.

I think im going to go with the diablo - but I'll wait until the contest is over (in case i win that programmer):lol:. And my budget is a bit tight. I turn 16 and will start actually driving in 2 weeks - gas and insurance. yay. and i just spent $140 on detailing supplies today. So, all in time.
